American Journal of Medical Genetics Part A, Volume 191, Issue 1, Page 234-237, January 2023., 2023 Abstract Adenylosuccinase deficiency is a rare inborn error of metabolism. We present a newborn who died at 52 days of age with clinical features suggestive of severe epileptic encephalopathy and leukodystrophy of unknown cause. Post‐mortem examination showed an unusual vacuolar appearance of the brain.

Cryo-EM structures demonstrate human IMPDH2 filament assembly tunes allosteric regulation
eLife, 2020 Inosine monophosphate dehydrogenase (IMPDH) mediates the first committed step in guanine nucleotide biosynthesis and plays important roles in cellular proliferation and the immune response. IMPDH reversibly polymerizes in cells and tissues in response to

Role of HIV RNA structure in recombination and speciation: romping in purine A, keeps HTLV away [PDF]
Microbes and Infection (2014) 16, 96-103, 2013 Extreme enrichment of the human immunodeficiency virus (HIV-1) RNA genome for the purine A parallels the mild purine-loading of the RNAs of most organisms. This should militate against loop-loop "kissing" interactions between the structured viral genome and structured host RNAs, which can generate segments of double-stranded RNA sufficient to trigger ...

Cardiovascular Pharmacology of Purines [PDF]
Clinical Science, 1997 1. This review focuses on the extracellular actions of ATP and adenosine, and in particular their role in cardiovascular regulation. 2. ATP serves as a co-transmitter within the sympathetic nervous system, and is also released from endothelium and aggregating thrombocytes.

Magnetic circular dichroism within the Algebraic Diagrammatic Construction scheme of the polarisation propagator up to third order [PDF]
, 2022 We present an implementation of the B term of Magnetic Circular Dichroism within the Algebraic Diagrammatic Construction (ADC) scheme of the polarization propagator and its Intermediate State Representation. As illustrative results, the MCD spectra of the ADC variants ADC(2), ADC(2)-x and ADC(3) of the molecular systems uracil, 2-thiouracil, 4 ...

A Generalization of the Auslander-Reiten Conjecture for the Bounded Derived Category [PDF]
Archiv der Mathematik: Volume 98, Issue 6 (2012), Page 507-511, 2011 We study the bounded derived category $\D^b(\Rmod)$ of a left Noetherian ring $R$. We give a version of the Generalized Auslander-Reiten Conjecture for $\D^b(\Rmod)$ that is equivalent to the classical statement for the module category and is preserved under derived equivalence.

Potential Mechanisms Connecting Purine Metabolism and Cancer Therapy
Frontiers in Immunology, 2018 Unrestricted cell proliferation is a hallmark of cancer. Purines are basic components of nucleotides in cell proliferation, thus impaired purine metabolism is associated with the progression of cancer.
